Subregional reflection seismic section (a) and interpretation (b) trending from the onshore in the SW on the left-hand side, and towards the NE crossing the coastline to the offshore (location shown in Fig. 2). The AFK High is host to the Abu Hadriya–Fadhili–Khursaniyah fields, all of which are outside of this line of section. This section, and the others in this paper, is composited from 3D and 2D surveys. This section features the only seismically imaged Hormuz salt intrusion (as interpreted) onshore Saudi Arabia. Overall, the section shows a variation in style from the Hormuz salt basin (e.g. Karan salt-cored fold), towards the SW across the original Hormuz basin margin and beyond to areas of Hormuz non-deposition, where the Phanerozoic rests directly upon pre-Hormuz basement. The colour coding in this and the other regional seismic lines presented in this paper ties to the megasequences highlighted in Figure 3. The timeslice in (a) shows a plan view of the Karan structure at 2 s TWT. This timeslice intersects Permian and Triassic strata; top Hormuz is much deeper, therefore the salt is not visible. Inset seismic in (b) the Hormuz basin margin shows shingled, possibly clinoformal stratal patterns. Cambrian–Devonian interpretation is largely obscured by seismic multiples, and is based on subtle reflections and offset well control. VE, vertical exaggeration.

Neoproterozoic – Early Cambrian Hormuz Salt Basin was a hyper-saline basin in a rift terrane. It was subdivided into three sub-basins of salt deposition; (1) South Gulf, (2) North Gulf and (3) Widyan Basins by (4) the Qatar Arch and (5) the Amar Arc. Facies patterns suggest that the basin was open to normal marine water toward the northeast (6) and that clastic facies were deposited along the shoreline toward the west and northwest (7). Faults (black, dashed lines), Hormuz lithofacies and locations of salt diapers are from Talbot and Alavi (1996, their figure 10). Faults (black, solid lines) are from Al-Husseini (2004, his figure 2, map of mid-Carboniferous outcrop, Saudi Arabia). Neoproterozoic – Early Cambrian lithofacies in Iraq (yellow [clastic] and pink [salt] diagonal striped polygons) are from Jassim and Goff (2006, their figure 8-2). The location of Amar Arc is from Al-Husseini (2000, his figure 1). The western and southern Gulf boundaries are generalized from depth to basement map in Konert et al. (2001, their figure 2). Jabal Sanam is the isolated salt diaper located in southern Iraq.

Subaerially exposed extrusive Hormuz salt sheets in the Zagros foreland in Iran. (a) Extrusive salt sheet sourced from the Kuh-e-Namak (Dashti, western Fars) salt dome. This outcrop view shows the south of two salt glaciers flowing from this salt plug. The feeder for the sheet is below the summit dome in the upper right of the photograph, and the main salt glacier flows off to the right. The remnant of the salt preserved on the canyon wall suggests that the present subsidiary flow is a wasted remnant of a much larger salt glacier. Dissolution produced residual gypsite soil, but only scattered patches of this soil remain because of erosion by rainfall runoff.
